Analog Discovery 2 not being recognized

[cetapc]

Hello,

I have a bunch of computers that are not recognizing the Analog Discovery 2 board.  The comptuers are running Windows 11 and the newest version of Waveforms (3.20.1_64bit.).  This device with the USB cable works fine with the same install of Waveforms and Windows 11 on my desktop computer, but not the ones in the lab.  The only difference is the other software installed and the lab machines were sysprepped before deploying.  The USB serial Port (COM4) says that the device is working properly when the AD2 is plugged in.

I have followed these steps.

 - USB Serial Converter, without warning

- Restart the computer.

- Reinstall WaveForms, including the Adept Runtime section. ( I did a complete uninstall, reboot and install here)

- Other application might have erased the USB controller EEPROM (FT_Prog, programming cable drivers...)

 Use the "My device is not listed" button in WaveForms application Device Manager to reprogram the EEPROM.

The "My device is not listed" option causes Waveforms to crash.  I can send the Event Viewer log if needed.

Is there something else I can try?

Thank you for your time.

Hi @cetapc

COM port should not show up with Analog Discovery. This is disabled in EEPROM config but it can be force enabled from software and an app/service keeping the COM busy prevents access to the device.
1. Make sure to uncheck "Load VCP" then reconnect the device.

I don't know why would the "My device is not listed" crash. This tries to load the FTDI library dynamically and it is safeguarded all around... may be caused by a buggy library version.

2. Make sure the driver version is new.
The latest is included in the WaveForms installer, available on Windows Update and here https://ftdichip.com/drivers/d2xx-drivers/
https://www.ftdichip.com/Drivers/CDM/CDM v2.12.36.4 WHQL Certified.zip

 

3. If the Windows does not want to load the new driver for the device, disconnect it, remove the driver files like shown here and reinstall the new driver.

Hello,

Thank you for the reply.  There is no Advanced tab in the driver window.  I removed and reinstalled the USB FTDI driver.  The attached images are screenshots of the driver window and an error log.  I also included the crash log for Waveforms with the "device not listed" then click "search for device".  It crashes every time.  This doesn't work on a lab full of computers.

Hi @cetapc

Try "Disable device" on the COM port opened for AD2, instead of restart reconnect the device, then open the "USB Serial Converter" and uncheck "Load VCP"
I hope this helps...

 

The crash is strange, I get the following when the device is blocked by COM:

Hello,

I uninstalled the USB Serial Converter and USB Serial Port drivers.  Then installed https://ftdichip.com/drivers/d2xx-drivers/ and it worked!  Thank you.
